Hi!
I have exactly this problem:
panda3d.org/forums/viewtopi … f095d28dd8
But I can not make it work properly, use this example:
self.accept(“mouse1”, self.LCPrep)
def LCPrep(self):
self.acceptOnce(“mouse1-up”, self.LCResponse)
def LCResponse(self):
self.performMousePicking()
that’s what I do wrong? 
thanks all
Did you put state = DGG.NORMAL in your frame’s constructor?
Thanks!
Yes:
FrameContenedor = DirectFrame(state = DGG.NORMAL, image=self.barra,image_scale=(3,1,0.25),image_pos=(-1,0,0.25),
frameSize=(-4, 1, -1, 0.5),
pos=(1, -1, -1))
self.accept(“mouse1”, self.LCPrep)
def LCPrep(self):
self.acceptOnce(“mouse1-up”, self.LCResponse)
def LCResponse(self):
self.performMousePicking()
.

if you want to prepare my code and shipping…
Thanks!
So it’s working correctly now?
I am working with Tut-Chessboard modified example.
I need that when the mouse is over the DirectFrame not interact with the chessboard.
Do not know how to use the functions LCPrep, LCResponse and self.accept (“mouse1” self.LCPrep)
thank you very much for your help!

self.squares[i].setColor(HIGHLIGHT)
self.hiSq = i
return Task.cont
w = World()
run()Okay, to use the solution I used you just need to change the mouse picking so that it isn’t a task. You only want to mouse pick when the mouse button is actually clicked.
Change
self.mouseTask = taskMgr.add(self.mouseTask, 'mouseTask')
def mouseTask(self, task):
if self.hiSq is not False:
self.squares[self.hiSq].setColor(SquareColor(self.hiSq))
self.hiSq = False
if base.mouseWatcherNode.hasMouse():
mpos = base.mouseWatcherNode.getMouse()
self.pickerRay.setFromLens(base.camNode, mpos.getX(), mpos.getY())
self.picker.traverse(self.squareRoot)
if self.pq.getNumEntries() > 0:
self.pq.sortEntries()
i = int(self.pq.getEntry(0).getIntoNode().getTag('square'))
self.squares[i].setColor(HIGHLIGHT)
self.hiSq = i
return Task.contto
self.accept("mouse1", self.LCPrep)
def LCPrep(self):
self.acceptOnce("mouse1-up", self.mousePick)
def mousePick(self):
if self.hiSq is not False:
self.squares[self.hiSq].setColor(SquareColor(self.hiSq))
self.hiSq = False
if base.mouseWatcherNode.hasMouse():
mpos = base.mouseWatcherNode.getMouse()
self.pickerRay.setFromLens(base.camNode, mpos.getX(), mpos.getY())
self.picker.traverse(self.squareRoot)
if self.pq.getNumEntries() > 0:
self.pq.sortEntries()
i = int(self.pq.getEntry(0).getIntoNode().getTag('square'))
self.squares[i].setColor(HIGHLIGHT)
self.hiSq = i
returnIf you make that change, clicking on the frame won’t initiate a mouse pick, because the “mouse1” event will be blocked by the frame and self.LCPrep won’t be called. If self.LCPrep isn’t called, the program won’t accept “mouse1-up” either, and self.mousePick won’t be called.
hi! Sorry for the delay.
thanks for your help, but could not solve my problem with your code, I do not need to click so that there is interaction, I just need that there is no interaction when the mouse is above the directframe. I will try to solve the problem with
panda3d.org/manual/index.ph … ay_Regions
Thanks for your help. I hope you help me later:)
yeah, if you’re not looking for click based interaction, then the solution above is no good to you.
